Azur Frost Petrol — Sculpture by Bertil Vallien | Kosta Boda Artist Collection

Azur Frost Petrol by Swedish glass master Bertil Vallien is part of the renowned Kosta Boda Artist Collection. Cast in a graphite mold at Kosta Glassworks, the sculpture features Vallien’s signature face motif—sandblasted into the surface of the petroleum-blue glass for a striking, textured effect.

A bold, contemplative work of art, Azur Frost Petrol embodies Vallien’s timeless exploration of form, color, and symbolism in glass.
